LAMP-SHADE.

Specification of Letters Patent.

Patented J an. 9, 1917.

To all whom it may concern:

Be it known that I, FREDERICK 0. SMITH, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Lamp-Shades; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in

Figure 1 a top or plan view of a lamp shade constructed in accordance with my invention. Fig. 2 a transverse sectional view of the same. Fig. 3 a transverse sectional view at right angles to the position shown in Fig. 2. Fig. 4c a side view of the stud, detached.

This invention relates to an improvement in lamp shades such as are commonly applied to the bulbs of incandescent lamps so as to be self-supporting thereon. These shades consist of a shell with some clamping means for engaging with an electric light bulb.

The object of this invention is to provide means for connecting an attaching device with a shade so that the parts may be finished before they are assembled and without the use of solder, which would injure the finish; and the invention consists in the construction as hereinafter described and particularly recited in the claims.

In carrying out my invention, I employ a shell 5 which is struck up from sheet metal into semi-spherical form with an outwardly extending flange 6 at its edge. In the center of the shell is a hole 7 in which is secured a stud 8, which stud is larger in diameter than the diameter of the hole 7 and provided with a reduced portion or neck 9 which will pass through the hole 7 and upset outside the shell so as to interlock the stud with the shell. In the end of the stud is a slot 10 to receive the central swaged portion 11 of a Wire yoke 12 each end of which is bent into ring shaped parts which stand parallel with each other. The swaged portion of the wire-holder is inserted into the slot 10 and the end of the stud upset so as to firmly interlock the wire holder stud, and hence lock it cent-rally in the shade beyond the edge of which the rings project. The sides of the wire holder are adapted to be sprung over an incandescent electric lamp bulb, and so that the shade may be turned to any desired angle with relation to the bulb, it being held in position by the friction of the wire holder. This construction permits the inside, as well as the outside of the shell to be finished by buffing or otherwise before the parts are assembled, and the ring entered into the stud and the end of the stud inserted through a hole in the shell and upset in a suitable press so as to interlock the wire-holder in the stud and interlock the stud with the shell, thus avoiding the use of solder the heat of which would mar the finish of the inside or outside of the shell.

I claim 1. A lamp shade comprising a shell formed with a central opening, a stud larger in'diameter than said hole and formed with a neck adapted to extend through said hole outside of which it is upset, said stud also formed with a transverse slot, and a wireholder entered into said slot the side walls of which are compressed against the said holder.

2. A lamp shade comprising a metal shell formed with a flange and with a central hole, a stud larger in diameter than said hole formed with a reduced portion adapted to extend through said hole and project beyond the outer surface of the shell upon which it is upset, whereby the stud is interlocked with the shell, said stud formed with a transverse slot, combined with a wire holder swaged at its center to enter said groove in the stud, the walls of which are upset to interlock the holder with the stud, the ends of said holder projecting outward from said stud and beyond the edge of the shell, the ends of the wire turned into ringshape which are arranged parallel with each other.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.

FREDERICK C. SMITH.
